To MU elf/01m it may cof/wem lle it known that we, Vieron RILEY and tf'r"naar dimm', subjects of the King \of (lia-fat liritain, both residing`at Hollybank, Rad-tord Road, Coventry, England, have invented new anduseful Improvements in Detachable Wheels, of which the following aspecification, v

This invention relates to the means for securing detachable wheels ontheir hubs. Such wheelsare commonly secured by a nut or ring which4screws onto a thread vcut on. the outer end of the inner or permanenthuh and hears afgainst'the outer end of the detachable hubxwhile lockingmeans such as a to )thed ringl or pawls carried by the nut engage teethon the detachable hub and so present the -nut from becoming` unscrewed.

ne objects of the invention are to provide novel devices for insuringthe disengan-ing ot the locking means before the nut is turned therebyavoiding all possible damage tothe locking means and for making` itimpossible when the nut is nearly screwed home to remove from the nutthe Spanner which operates it until the locking means are completely inengagement.

ln the drawings which illu trate the invention Figure 1 is a sectionshowing the nut with the spanner placed in position on it the toothedlocking ring being in engagement with the hub shell; Fig. 2 is a similarsection with thelocking ring disengaged from the hub shell; Fig. 3 is'asection ot the nut; Fig. 4 an end elevationthereof; Fig. 5 is a section'ot' the locking'ring; Fig. Gan elevation thereof; Fig. 7 is a sectionof the claw plate; Fig. 8

an elevation thereof; Fig. 9 is a detail view in section showing theinclines on the claw plate; F ig. 10 is a sect-ion of the cover plate,and Fig. 11 an elevation thereof; Fig. 12 is a section and Figs. 13 and14 a. :face and rear view of the spanner; Fig. 15 is a seetion on theline A-A, Fig. 17, of a modification showing the locking pawl engaged;Fig. 1G is a similar Section showing the locking pawl disengaged; andFig. 17 is a face view ol" the spanner placed in position on the'locking nut.

The nut 1 consists of two co-aXial cylinders, an inner cylinder 2 and anouter cylv inder 3, connected together by a flange 4.l near their outerends and carries as is usual a dra w-otf rirfr 5. This ring is screwedon to a left hand screw thread around the inner end of the cylinder 2.lFitting on to the cylinder 2 between the flange et and the draw oit'ring 5 is a toothed locking ring 6 which engages with teeth cut on acollar- 8n forming part ofthe detachable huh or hub shell 8; the twosets of teeth being forced into engagement with each other by springs 7lying between the ring G and the flange 4.' Surrounding the innerCylinder 2 0n the outer side of the liange is a claw plate 9.

The toothed locking ring 6 has projecting from its outer face pins l()which pass through holes 11 in the flange 4 of the nut 1 and throughslots 12 in the claw plate 9. The pins 10 have notches 13 (Fig. 5) cutin them which engage with inclines 14. (Figs. 8 and 9) on the claw plateso that when the latter is turned relatively tothe locking ring G thepins 10 and with them the locking ring S are drawn outward thus.compressing the springs 7 and disengaging the teeth ot the ring G fromthe teeth of the hub shell. turn together while the nut and claw platehave a limited movement relatively 'to each other. It will he observedby reference to Fig. 8 that the slots 12 are considerably longer thanthe diameter of the pins which admit of' this relative movement. mally,or when the locking ring is engaged with the huh shell the pins 10extend through portions of the slots which are not provided with'theinclines 11 and said portions of the slots are somewhat longer than thediameter of the pins 10. A cover plate 15 is preferably provided on theouter side offthe (':lafw plate 9. This cover platey 15 has holes '18 tosteady the pins 10 which project 'from' the toothed locking ring 6 andthe cover plate ,gives a smooth outside tace to the nut 1. `It isprevented from movement relative to the nut 1 hy twotongues 16 .formedin its here and fitting into two cor responding slots 17 in the nut.

The claw plate 9 is normally locked in one position relatively to thenut 1 andlocking ring G by means of a spring pressed ball 19 which liesin a hole 20 in the iiange 4 and engages with a recess 21 in the clawplate 9. The ball 19 normally holds the claw plate in place preventingaccidental movement of said plate relatively to the ring 6 when theparts are in lockedV position,l but the ball is readily dislodged fromits'socket 20 when the claw plate is operated by the Spanner. lVithoutvsome such device the claw plate might have to be shifted by Thus thering 6 and thenut 1 Norhand in `order to bring it intoproper position toenable the SpannerV to be put -on or taken ott'. The inner end of theouter cylinder 3 has a fiange 22 'projecting radially' from it, the.diameter of this fiange beinggreater than that of the claw plate 9.NVide notches 23 are cut the whole length' of the outer cylinder 3(including its flange) andl in the cl'aw plate 9. At'one end ofthe cy'lindrical body are fixed .segmental flanges 27 the internal diameter of'which is sufiiciently largevto enable them to be passed over the clawplate .9, but not large enough to pass thev flange 22 of the cylinder 3of the nut l except at the wide notches 23 in which they are a closefit.A At the other side of the cylindrical body of the Spanner 25 areinwardly projecting plates 28 which come upon the ends of the pins 10 ofthe locking ring 6.

lVhen the Spanner 25 is applied, the fianges 27 pass through the notches23 in the flange. 22 ofthe nut and thelreys' 26 of the Spanner pass intothe notches 23 of the nut and the notches 24 of the claw plate', andwhen thev Spanner is turned in either direction the .flanges 2T comebehind the flange 22 of the nut and the Spanner cannot be Withfdrawnwhen the parts are in this position.

Such'rernoval of thev Spanner can only take place when ,the -latter isturned back againy vuntilthe anges 27' thereof come into line y with thenotches 23. ofthe nut flange 22 at Which time the keys 26 of theSpanner. are also in line with the notches 23 and 24.

`Assuming thatl the Wheel is placed on the permanent huband lockedthereto and it is desired t0 unfix the wheel or remove it from thepermanent hub. the Spanner is ap plied to `the nut, the notches 24 and23 being in line and permitting-the-fianges'27 to pass into a verticalplane behind the nut with the keys 26 in the notchesY 24 and 23.The'spanner is then turned to the left. Inasmuch as'thc keys 26 fitclosely in the notches 24 and loosely in the notches 23, the claw plateis first moved relatively to the locking plate 6 and to the nut. r["hismovement of the Spanner causes the plates 28 carried thereby tobewithdrawn from the' vouter end of thepins l0 of the locking ring,

'thenthe claws or inclines on the claw plate engage the pins l0 and movethem outward causing; the locking plate to separate from the detachablehub.- This is done before the nut is turned and thus any strain on theteeth is avoided. -By the continued movement of the Spannertto the leftthe nut may be unscrewed and the Wheel Withdrawn. The Spanner may beleft on the nut or it may be removedtherefrom by holding the nut andturning the Spanner a short distancetothe right until the flanges 2Scome into line with the notches 'Io replace the ivhe'el, assuming thatthe Spanner isv remove h the nut is first applied to the permanent hub,and the Spanner is placed on the nut, the flanges 2T passing through thenotches 23 in the fiange 22 of the nut and the keys 26 entering thenotches tothe right, the flangesv 2T of the Spanner Will pass behind theflanges 22 of the nut, andv when in this position the Spanner cannot beWithdrawn. At this Vtime the pins 10 do not project from the nut and ifthe movementfof the Spanner to the lright be teeth on the hub shell.

When the nutis nearly screwed home, the teeth von the toothed ringchatter over the teeth on the hub Shell, theA pins 10 being outer end ofthe hub.. If the movement be completely engaged with .the teeth on thehub shell, the parts will be securely locked from the outer end of thehub and the spannermay be turned a Short distance'in reverse direction.e'. e.; to the left untii the flanges 27 come into line with the notches23 rof the huh flange 22, then the Spanner may be Withdrawn. But if theteeth of the ring 6 touch the teeth ofthe detachable huh. the yengagement of the teethv is not complete. e. (7;, if the ends of theteeth merely engage each other the pins l0 Will project 'from the outerend of the hub and it' it be attempted to move the Spanner inthercvei'se direction.

vpath of the plates 28-/Will prevent a sufficient movement to bring theflanges 27 into line with the notches 23 and hence' the Spanner cannotbe Withdrawn from the nut. lt is first necessary to turn the nut to agreater extent to the right until the teeth are completely engaged sothat the pins 10 will not project., and then the Spanner can be turnedback to brine; its flanges 27 into hue with the notches so that v4heSpanner can be easily removed.

It will be observed that these operations unfixing the wheel` the teethof thelot-lsingl device :irc first. Withdrawn from engagement with 'thehub shell when the Spanner lirst moved and in screwing on the nut. arigid 24 and 23.` 'If noW the Spanner beturnedcontinued until the teethon the ring are and at that time'the pins donot project continued thenut will he screwed home, the, teeth on the ring 6 being' made to engagethev alternately projected and withdrawn at the z'. e., to the left` thepins being non* in the are automatic, that is to say, in removing or epart of thel locking device projects into 'the path of a rigid part ofthe Spanner when the teeth ot' the locking device and 'the hub tis notnecessary as in some prior con-y structions to operate or adjust somedevice by the hand inv order to etl'ect these results. llhe lockingdevice shown in F ig. l is in etiect a pawl with an extended toothedfsun.tace and with a plurality of pins or projecting parts which are maderigid with the toothed surface. A(')ne or more independent pawls may beemployed if desired.

ln the torni of invention shown in Figs. l5, 16 and 17 the clawA plateis omitted but the nut l is ol' the kind shown in Fig. 3 be' .ingprovided with wide notches 23 (Fig. 1T) formed in the part 8 of the nutlas Well as in the iange 23. lin's or pawls 29 are rigidly secured to aring or cover plate 30 which moves lin and out with them. The plate 3Q'is attached' to bolts 302l extending through thimbles 30b in the nut andsprings 7a engage theheads 3()C of the bolts and tend to draw theY coverplatev inward and to cause the pawls 29 to engage the teeth of the hubshell. The cover plateB() carries lugs 38 having` inclined ends as shownfor the purpose presently explained.

The spanner Q'is adapted to tit over the nut and it is formed with keysQ6 similar to those. before deseril; ed'which enter the relatively wide'notches in the part 3 of the` nut and in its tiange/IQ. The spanner is,as he'tore described, formed with segmental tianges 2T which operate inthe manner before specified, 'z'. e., these flanges when the spanner isbeing` applied pass through the notches 23 ot the hub and its flange,and when the Spanner is turned in 'either direction the flanges 2i' comebehind the ilange Q2 and the span'ner cannot be withdrawn. The spannercarries on its liront ifaeo plates 3iwhich, as shown in Fig.` 17, attimes are disposed in front of the lugs 33. The spanner also carrieslugs 32 having inclined ends which are adapted to engage the h-igs 33.Assinning that the wheel is `iiXed t thc-permanent hub and it is desiredto withdraw it or nnx it, the Spanner is applied in the manner beforedescribed and is turned to the lett. The plates 34 uncover the lugs andthe lugs 32 enter behind the lugs and cause the cover plate 3Q with thepawls 9 to be moved outward against the tension of the springs 7a. Bythis movement the pa-wls are disengaged from the hub shell and bycontinued movement t0 the left the wheel may be withdrawn.

To replace the Wheel the nut' is applied to the permanent hub and theSpanner is applied to the nut, thenotches 23 at this time permitting theflanges 27 to pass to a vertical plane behind the flange 22. of the nut,then ifQthe spanner`be turned tothe right the ilanges 2T will comebehind the flange 22 and the Spanner cannot at this time be removed fromthenut. By turning the spanner asuilicient number of times the nut isscrewed on and the toothed pawls chatter over the teeth of the permanenthub and if the nut be suliiciently turned the pawls and the hub will be.completely engaged. It the pawls are not completely' engaged with thehub shell, the cover plate 30 will be projected from the front end ofthe nut and the lugs 33 will lie in the path of the plates 34 and willprevent the Spanner from being turned on the nut sufliciently to causethe flanges 27 to .come into line with the notches 23. It will first benecessary to tnrn the spanner tothe right sufficiently to cause thepawls to completely engage the teeth ot the detachable hub` after whichthe Spanner may be turned backward or to the lett sntticientlyA topermit it to be withdrawn. In this `case alsoa part rigidly connectedwith` the pawls is made to come into the path of a part rigidlyconnected with the spanner to prevent the premature withdrawal of thespanner.
